Yes, we keep saying that. Prophets are fallible as men.
Sorry this is so late, I am playing catch up. The absolute fallibility of all men, including prophets reminds me of what is sometimes referred to as the Psalm of Nephi. Talk about a human being, who understood the frailty of the flesh and all that it entailed. I know this is long, but it's one of my favorite passages from the book of Mormon. Sorry to spam it:
2 Nephi 4:
16 Behold, my soul delighteth in the things of the Lord; and my heart pondereth continually upon the things which I have seen and heard.
17 Nevertheless, notwithstanding the great goodness of the Lord, in showing me his great and marvelous works, my heart exclaimeth: O wretched man that I am! Yea, my heart csorroweth because of my flesh; my soul grieveth because of mine iniquities.
18 I am encompassed about, because of the temptations and the sins which do so easily beset me.
19 And when I desire to rejoice, my heart groaneth because of my sins; nevertheless, I know in whom I have trusted.
20 My God hath been my support; he hath led me through mine afflictions in the wilderness; and he hath preserved me upon the waters of the great deep.
21 He hath filled me with his love, even unto the consuming of my flesh.
22 He hath confounded mine enemies, unto the causing of them to quake before me.
23 Behold, he hath heard my cry by day, and he hath given me acknowledge by bvisions in the night-time.
24 And by day have I waxed bold in mighty prayer before him; yea, my voice have I sent up on high; and angels came down and ministered unto me.
25 And upon the wings of his Spirit hath my body been carried away upon exceedingly high mountains. And mine eyes have beheld great things, yea, even too great for man; therefore I was bidden that I should not write them.
26 O then, if I have seen so great things, if the Lord in his condescension unto the children of men hath avisited men in so much mercy, cwhy should my heart weep and my soul linger in the valley of sorrow, and my flesh waste away, and my strength slacken, because of mine afflictions?
27 And why should I yield to sin, because of my flesh? Yea, why should I give way to temptations, that the evil one have place in my heart to destroy my peace and afflict my soul? Why am I angry because of mine enemy?
28 Awake, my soul! No longer droop in sin. Rejoice, O my heart, and give place no more for the enemy of my soul.
29 Do not anger again because of mine enemies. Do not slacken my strength because of mine afflictions.
30 Rejoice, O my heart, and cry unto the Lord, and say: O Lord, I will praise thee forever; yea, my soul will rejoice in thee, my God, and the rock of my salvation.
31 O Lord, wilt thou redeem my soul? Wilt thou deliver me out of the hands of mine enemies? Wilt thou make me that I may shake at the appearance of sin?
32 May the gates of hell be shut continually before me, because that my heart is broken and my spirit is contrite! O Lord, wilt thou not shut the gates of thy righteousness before me, that I may walk in the path of the low valley, that I may be strict in the plain road!
33 O Lord, wilt thou encircle me around in the robe of thy righteousness! O Lord, wilt thou make a way for mine escape before mine enemies! Wilt thou make my path straight before me! Wilt thou not place a stumbling block in my way—but that thou wouldst clear my way before me, and hedge not up my way, but the ways of mine enemy.
34 O Lord, I have trusted in thee, and I will trust in thee forever. I will not put my ctrust in the arm of flesh; for I know that cursed is he that putteth his trust in the arm of flesh. Yea, cursed is he that putteth his trust in man or maketh flesh his arm. 35 Yea, I know that God will give liberally to him that asketh. Yea, my God will give me, if I bask not amiss; therefore I will lift up my voice unto thee; yea, I will cry unto thee, my God, the rock of my righteousness. Behold, my voice shall forever ascend up unto thee, my rock and mine everlasting God. Amen.
